Hi,
=20
This is not allowed at Union college either. I agree that tracking one
down could be difficult.

Subject: multihomed resnet users

=09
Is anyone having issues with rooms connected to Resnet via
ethernet and an outside internet connection like a cable modem or DSL?
Our internet connection is no longer the fastest service around.
Evergreen housing residents who want faster internet connections are
signing up for cable modems, which seems reasonable to me as it makes
them happy and gets traffic off Resnet. However some people in our
campus IT department are very nervous about the possibility of a
multihomed machine in Resnet circumventing the campus firewall. Resnet
is a network segment inside our campus firewall so students can access
file shares on student use servers in our labs, but the segment can't
access our administrative db servers. I don't want to move Resnet
outside the firewall as that would cut off access to machines in the
labs.
I've updated our RUP to prohibit multihomed devices, but that
doesn't make our administrative IT folks feel much better. I'm not even
sure how to detect a multihomed machine on our network, the only one
we've found so far was easy to track down as it was also a rogue dhcp
server. Any advice is greatly appreciated.
Thanks,=20
